The first two terms make \(T\)  not a Lagrange multiplier anymore but a propagating superfield. Next the authors of [1]} have changed variables to make \(T\)  a canonical superfield and computed the masses of all scalars. However, unlike the authors of the ERG approach [2]},
Dall'Agata et al did not study the relation of their model to the original theory where \(T\)  is not a propagating field, by looking at the limit
\(Z_T= \beta \rightarrow 0 \ .\)
